Abstract

PURPOSE:To prevent a cursor position on a display surface from being moved even if a machine body is moved at a time other than the operating time by fitting a permanent magnet to be magnetically adsorbed to a position indicating device to a plane member consisting of ferromagnetic material. CONSTITUTION:An adsorbing member is made of a permanent magnet and a supporting member 16 is made of a nonmagnetic material. At the non-operation of the position indicating device 1, the leading ends of a spherical member 3 and the supporting member 16 of a movement detecting part are slightly floated from the surface of a desk. If the operator applies external force from the upper part of the machine body 1 downwards, the supporting member 16 fixed on a seesaw member S is projected downwards and the adsorbing member 15 is floated from the surface of the desk with a slight gap. Simultaneously, the spherical member 3 contacts the surface of the desk and the machine body 1 generates a signal corresponding to the movement. Since the adsorbing member 15 is adsorbed to the magnetic body on the desk at the non-operation of the machine body 1, the machine body 1 is not moved, and even if the desk surface is inclined, the machine body 1 is not also moved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a position pointing device used for pointing the position of a cursor within a display surface of a display in an information processing device.

(Prior Art) Moving a cursor within the display surface of a display by operating a cursor movement key is the most commonly used operating means in the past.

By the way, instead of using the above-described cursor movement keys as an operation means for moving the cursor within the display surface of the display, a position indicator configured so that a required position indicator signal can be obtained in accordance with the displacement of the aircraft body is used. It is also known that a device (mouse) can be used to manipulate the movement of a cursor within the surface of a display simply by moving it in any direction on the surface of the desk; 2.The latter means allows for simpler and easier operations for moving the cursor within the display surface of the display than the former means. It is also well known that using a mouse has been widely practiced.

The above-mentioned position pointing device conventionally includes a body movable in any direction using a flat member, and a movement amount detection section for detecting the amount of movement of the body.

and a signal conversion section that fractionates the displacement amount detected by the movement amount detection section into components in two orthogonal directions and generates signals corresponding to the magnitudes of the two orthogonal components, respectively. Specifically, for example, a spherical member for detecting the amount of movement that can be moved in any direction while in contact with the desk surface, and two directions orthogonal to the displacement of the spherical member for detecting the amount of movement described above. A signal conversion unit that decomposes into components and generates signals corresponding to the magnitudes of the two orthogonal components, or, for example, a pattern composed of a large number of orthogonal lines. A movement detecting section consisting of a light source and a sensor is placed on the second surface of the desk, and a movement detecting section consisting of a light source and a sensor is placed in the aircraft which is movable on the pattern described above, and the amount of displacement of the aircraft detected by the above described movement detecting section is provided. A typical example is one that is configured with an η transform unit that decomposes the signal into components in two orthogonal directions and generates signals corresponding to the magnitudes of the two orthogonal components. However, in conventional position pointing devices, the movement amount detection section is always operable, so it is difficult to operate when the operator takes his hand off the position pointing device. If the position pointing device moves on the desk due to the desk being tilted or for some other reason, the position of the cursor on the display screen may shift accordingly. In such a case, it is necessary to operate the position pointing device again to correct the position of the cursor.

(Objective) The present invention provides a position pointing device that does not have the above-mentioned drawbacks that have been a problem with conventional position pointing devices. It is an object of the present invention to provide an indicating device that does not move.

(Structure) Hereinafter, with reference to the accompanying drawings, a position indicating device of the present invention, that is, a body movable in any direction on a flat member, and a mechanism for detecting the amount of movement of the body described above will be described. A signal that decomposes the displacement amount detected by the IJ amount detection section and the movement amount detection section into components in two orthogonal directions, and generates a signal that corresponds to the magnitude of the two orthogonal components, respectively. In the position pointing device equipped with a conversion section, the distance between the movement amount detection section and the flat member is intentionally shifted by a larger distance than the normal distance during non-operation when no external force is applied to the aircraft body during operation. Move! 1lII: [i! ：A position indicating bag provided with a means to make the detection part inoperable, and
In the above-mentioned position indicating device, as a plane member which should be able to move freely on C and the aircraft body, a material composed of strong Fl+(P(1) is used. When no external force is present and there is no operation, F11 gate 1 between the movement amount detection section and the flat member is intentionally shifted by a distance greater than the normal distance, thereby rendering the movement amount detection section in an inoperable state. , we will explain in detail the specific content of the position pointing device using a permanent magnet that magnetically attracts the flat part H that includes a ferromagnetic material (i).

Reference numeral 18 denotes a separation member that comes into contact with the surface of the desk to separate the position of the bottom plate 2 of the position pointing device from the surface of the desk, and also allows the position pointing device to be easily moved on the desk. It is a member.

Now, the position pointing device of the present invention is designed so that the position of the cursor on the display surface of the display does not move even if the device moves on the desk while it is not being used for position pointing operations. In order to The distance between the detection section and the surface of the desk is intentionally shifted to be larger than the normal distance, so that the movement amount detection section is put into a non-operating state. , it moves f! In the case of the embodiment shown in the first drawing in which the spherical member 3 for detecting the amount of movement is used as the detection section, the position pointing device is in the non-operating state L as described above.
! l- When the spherical member 3 for detecting the amount of movement in the amount of movement detecting section rises from the surface of the desk, the desk and the spherical member 3
are in a non-contact state, the movement amount detection section becomes inactive, and the position indicating device to which the present invention is applied moves the pattern made up of a large number of orthogonal pieces of cotton to the surface of the desk. If the above configuration is such that a movement amount detection section consisting of a light source and a sensor is provided in the body which is movable with the above-mentioned putter, When the position pointing device is in a non-operating state as in the above, the spherical member 3 for detecting the amount of movement in the amount of movement detecting section is placed in a state floating above the surface of the desk, and the distance between the pattern on the desk and the sensor is In the position pointing device of the present invention, the body of the position pointing device In a non-operating state where no external force is applied from either side, the distance between the movement amount detection unit and the desk surface is intentionally shifted to be larger than the normal distance, and the movement amount detection Even if the position pointing device moves on the desk when not in operation, the cursor does not move on the display. 2 and 3 showing a longitudinal side view in a state in which the position pointing device of the present invention is not used for position pointing movements, and FIG. 5 showing a state in which the position pointing device of the present invention is used for position pointing movement This will become clear if we compare Figure 6.

C1 In the position indicating device of the present invention, in a non-operating state in which no external force is applied to the machine body l from above, the distance between the movement amount detection unit and the desk surface is larger than the normal distance. In order to avoid intentional displacement, a seesaw member S, a spring 17, and an adsorption member 1 are used in the illustrated embodiment.
5 and a fulcrum member 16 are used.

The seesaw member S is configured to be able to perform a seesaw operation inside the fuselage 1 while being supported by the spindle 14 on the fuselage 1. As clearly shown in FIG. A suction member 15 is fixed near one end of one member S (=J), and a fulcrum member 16 is fixed near the other end of seesaw member S. The means for supporting S by the support shaft 14 may be arbitrary, but for example, after the support shaft 14 is loosely fitted into a groove carved in the fuselage 1, the top plate 2 is covered from above. Measures such as the following may be adopted.

The adsorption member 15 fixed to the seesaw member S mentioned above and the fulcrum member 16 have a height j of the fulcrum member 16 which is slightly higher (shown as Δy3 in FIG. 7(b)). It is assumed that it is high and configured as C. In the illustrated example, the fulcrum member 16 is semispherical and the suction member 15 is semicylindrical. Figure 7(a) is the arrow X in Figure 7(b)
a It is a view seen from the force direction.

In addition, (c) in FIG. 7 is the arrow X in (b) in FIG.
, is a view seen from direction c.

The attraction member 15 described above is made of a permanent magnet.

Further, the fulcrum portion vi16 is made of a non-magnetic material.

The upper surface of one end of the seesaw member S supported in the body 1 by the support shaft 14 is strongly pressed by the elastic force of the spring 17, so that when the position indicating device is not operated, the above-mentioned suction member 15 protrudes from the bottom plate 2 and its tip is strongly pressed against the surface of the desk, whereby the position pointing device is displaced in a direction in which its body 1 is separated from the surface of the desk.

For this purpose, the spherical member 3 of the movement amount detection section in the position pointing device when not in operation is made to float above the surface of the desk by an interval indicated by Δy1 in FIG. 3, and the tip of the fulcrum member 16 is It is placed in a state where it is floating by Δy2 above the surface of the desk.

Next, during operation, as shown in Figure 5, when the operator touches the position pointing device to the body 1 and an external force is applied to the body 1 from above, In this case, the spherical member 3 of the movement amount detection section and the upper surface of the desk are in good contact. That is, the inner body 1 of the position pointing device has a 1. If an external force is applied from above to below, the seesaw member S will move as the aircraft 1 descends.
The fulcrum assembly 16, which is fixed to the
Go.

Finally, as shown in FIG. 7(b), the tip of the suction member 15 is raised from the surface of the desk? Then, the distance Δy3 is generated, and the spherical member 3 of the movement amount detection section is brought into good contact with the surface of the desk. A signal η is generated, and the cursor on the screen moves according to the movement of the position pointing device.

When the position pointing device is not operated, the suction member 15 fixed to the seesaw member S of the position pointing device protrudes downward from the bottom plate 2 as described above and is brought into contact with the surface of the desk 21A. However, since the adsorption member 15 is made of a permanent magnet,
When the desk is made of ferromagnetic material (for example, steel), the adsorption member 15 firmly adsorbs to the surface of the desk.
The position indicating device is held stationary.

Therefore, even if the surface of the desk is tilted as shown in Figure 6, the position pointing device will not move by itself.

If the desk or other flat member on which the position pointing device is to be operated is not made of a ferromagnetic material, the adsorption member 15 will not adsorb it. The position indicating device may be operated by placing a flat member made of a flat plate made of magnetic material with a rubber or plastic coating layer on top of the desk. In FIG. 5, J5C121 is a desk, 22 is a thin iron plate, and 23 is a rubber coating layer.

In the above case, if a pattern consisting of a large number of glands perpendicular to the rubber coating layer 23 is applied, the movement amount detection section can be used as a position indicator consisting of a light source and a sensor. The present invention is also effective in that it can be used satisfactorily when applied to a device. .

In addition, during non-operation, when there is no external force applied to the aircraft during operation, the distance between the displacement detection unit and the plane surface is larger than that of the regular Fri. In this manner, the movable wind detecting part is made immovable with 1 movable claw 1,
A surface indicating device F? is made of a permanent fossil that is carved into a flat ini member that is made of a ferromagnetic material and is magnetically attracted to it. Therefore, in the position pointing device of the present invention, the distance between the movement amount detection section and the flat member may be set to a regular distance, or the distance between the movement amount detection section and the flat member may be set to a normal distance, depending on whether the device is in use or not. ! ! j between the llR detection part and the plane member
Even if the position of the aircraft moves for some reason when it is not in use, i.e., when it is not operated, such as by intentionally shifting i'[fi by a greater distance than the normal distance, the display may be The position of the cursor on the display screen does not move, and if you use the position pointing device on a flat member made of ferromagnetic material, you can easily use the position pointing device on an inclined surface. This has the advantage of making it easier.
